boundary layer flow and heat transfer over a permeable stretching/shrinking sheet with a convective boundary condition

This paper concerns with the boundary layer flow and heat transfer over a permeable stretching/shrinking sheet in a viscous fluid, with the bottom surface of the plate is heated by convection from a hot fluid. the partial differential equations governing the flow and heat transfer are converted into ordinary differential equations using a similarity transformation, before being solved numerically. the effects of the suction, convection and stretching/shrinking parameters on the skin friction coefficient and the local nusselt number are examined and graphically illustrated. dual solutions are found to exist for a certain range of the suction and stretching/shrinking parameters. the numerical results also show that suction widens the range of the stretching/shrinking parameter for which the solution exists
